8 Claims. (c1. 8-2ll) v The present invention relates to cotton clothcotton fabric, bleached and mercerized, is parchhaving ornamentaleffects thereon andto methods of producing such cloth.

It has for some time been the practice in the art to form ornamentaldesigns on cotton fabrics by applying thereto in selected areas aparchmentizing agent thereby rendering these areas transparent.

It is an object of our invention to provide such a fabric, theornamental appearance of which is enhanced by permanent cookies orcrinkles formed in the unparchmentized areas. It is a further object ofour invention to enhance the ornamental appearance of such fabrics byproviding in the transparent areas very slightly darker or shadowy linesor portions. It is a still further object of our invention to provide aprocess whereby these ornamental effects may readily be obtained.

We claim: I

1. A cotton fabric having parchmentized areas and unparchmentized'areas,the uirparchmentized areas having shrunken portions and other unshrunkenportions puckered and standing out in relief, the parchmentized areasbeing smooth and having portions more sheer than other portions.

2. A cotton cloth having a pattern in relief and composed of relativelysmooth parchmentized areas and of unparchmentized areas permanentlycrinkled, said unparchmentized areas including strips of shrunkenmaterial and alternate strips of unshrunken material.

3. A cotton cloth having a pattern of smooth parchmentized areas andraised, crinkled unparchmentized areas within said pattern, said raisedunparchmentized areas being in part shrunk and in part unshrunk.

4. A process for treating cotton fabric which comprises parchmentizingthe fabric in a pattern and shrinking parts of the unparchmentized areaswithin'the pattern by a shrinking agent while preserving other adjacentparts of the unparchmentized areas'unacted upon by said shrinking agent,thereby producing a permanent crinkled effect in the saidunparchmentized areas.
